Alike PF or ESI, gratuity act does not require any registration as such. When a person quits a company and if he/she is eligible for gratuity, company has to pay the gratuity. Now in your case legally you are not bound to pay the gratuity. Nevertheless, it would be improper to leave an long-serving employee high and dry. He has served your organisation and now it is your time to acknowledge his services and go beyond the limits of the law and fulfil the employee-friendly practice.

As already discussed earlier, Payment of Gratuity Act 1972 is per se not applicable to your organisation. But if you wish to pay these loyal employees some amount towards ex gratia, you can do so on the lines of the PGA act ie 15 days salary per completed year of service, this is to be paid upon superannuation or separation. There is no legal binding, also there is a gratuity policy from the LIC where you can set aside specified sum each year so that you are not burdened at the end of the tenure of the services of these people. But if they are already 10 years old, you can have other methods to provide the same.
